People of all ethnicities are needed as background extras for a new movie starring Oscar winner Cate Blanchett that will be made in Pittsburgh.

Filming on the comedic drama "Where'd You Go, Bernadette" is scheduled for early July through late August. Extras will portray roles including business people, traveling passengers, families, elementary students, grandparents and construction workers.

"Where'd You Go, Bernadette" is based on the best-selling Maria Semple book about a quirky architect who goes missing before her family's trip to Antarctica. The story is narrated by the woman's 15-year-old daughter.

"Bernadette, her husband Elgin (a famed and genius computer scientist who leads the design team at Microsoft for Bill Gates's favorite project) and their daughter Bee live in Seattle. Bernadette (a notorious former architect) grants her daughter's wish, a family trip to Antarctica, and gets enveloped in the plans. She does this as a coping mechanism because for years she has lived in a city she hates with a life she never wanted, and is just barely holding onto her sanity. After everything goes wrong, Bernadette suddenly disappears, leaving Bee to search through old documents and emails to try to find her mother. While doing this, she discovers her mother's troubled past."
